Speedmaster 1861 movement accuracy

I’m not too fanatical with accuracy as long as it’s running within spec, but i recently downloaded the WatchTracker app and I’ve been wearing each watch a little longer before rotating. 6 days isn’t the largest sample size, but a net +0.2 spd is much more accurate than i would have suspected.

After sitting unwound for a few weeks, the speedy went 3 days losing time before running fast as it usually does, netting down and appearing more accurate than I suspect it will be as i continue to wear it.

My 1861 hacks every time unless fully wound. Not complaining after having several Seiko SKXs and having to really turn the crowns backward to stop the movements.
